256GB DDR5 4800 ECC RDIMM Kit

This 256GB kit contains eight 32GB DDR5 4800 ECC RDIMM modules built for the THINKMATE GPX-XH8-22S4-8GPU server. Registered buffering and on-die ECC protect data integrity in multi-GPU compute and virtualization workloads. The 1.10V operating voltage matches the platform specification.

Sustained load stability

Modules are stress tested under load before shipment to verify reliable operation during extended training or rendering runs. The 2Rx8 organization and CL40 latency deliver consistent throughput without thermal throttling in densely populated sockets. Registered design reduces electrical load on the memory controller at full population.

Eight-module installation

Eight 288-pin RDIMMs fill every slot on the target platform, so installers must follow the motherboard population sequence exactly. No heat spreaders are fitted; ensure chassis airflow meets the server vendor guidelines. Mismatched population order is the most common cause of POST failure.

Questions about this item

How much power does the 256GB DDR5 4800 kit draw at its rated 1.10V when the server runs continuously?

Each module operates at 1.10V, the standard DDR5 voltage, so total power scales with the 256GB capacity and the server workload rather than a fixed per-kit figure.

What must the ThinkMate GPX-XH8-22S4-8GPU already have for this 8×32GB ECC RDIMM kit to function?

The server needs eight free 288-pin DDR5 RDIMM slots and a CPU or memory controller that supports registered ECC DDR5 4800 at CL40.

Will the 2Rx8 registered ECC modules run at 4800 CL40 if slower DDR5 DIMMs are already installed in the same system?

The memory controller typically clocks all populated slots to the lowest common speed, so mixing with slower DDR5 will drop the kit to that lower rate.
